There are about 1432 clinical studies being (or have been) conducted in Croatia. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The purpose of this study is to compare the effectiveness and safety of golcadomide in combination with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) chemotherapy vs placebo in combination with R-CHOP chemotherapy in participants with previously untreated high-risk large B-cell lymphoma (LBCL).
Oxidative stress and endoplasmic reticulum (ER) stress play a key role in tubular damage in both acute kidney injury and chronic kidney disease (CKD). Oxidative stress in the kidneys promotes renal vascular remodeling and increases preglomerular resistance. These are key elements in hypertension, acute and chronic kidney injury, as well as diabetic nephropathy. Chronic renal hypoxia is highlighted as the final common pathway to end-stage renal disease (ESRD). MicroRNA molecules (miRNA) also play an important role in these processes. MicroRNAs (miRNAs) are regulators of gene expression and play a role in the progression of renal ischemia-reperfusion injury. Although the pathophysiological contribution of microRNAs (miRNAs) to kidney damage has also been highlighted, the effect of miRNAs on kidney damage under conditions of oxidative and ER stress remains understudied.
In the frame of this proposal investigators will test the hypothesis that high normal blood pressure (prehypertension; PreHT) induces systemic endothelial dysfunction and endothelial activation in both micro- and macrocirculation, reduces re-endothelialization potential of human endothelial progenitor cells (EPCs) and increases the level of endothelial extracellular vesicles (EVs), which are accompanied by increased oxidative stress level. Furthermore, initial vascular and left ventricle (LV) remodeling contributes to changes in systemic hemodynamics and may be influenced by altered regulatory role of renin-angiotensin system (RAS) and autonomic nervous system (ANS) in PreHT but otherwise healthy individuals. To distinguish high normal blood pressure effect from those considered normal or high, study will be performed in three groups of individuals: prehypertensive (BP 130-139/85-89 mmHg), hypertensive (stage I, BP 140-150/90-100 mmHg), and controls (BP less than or equal to 129/85 mmHg). Altogether, the impairment of normal vascular relaxation mechanisms, endothelial activation as well as vascular and LV remodeling could play crucial role in increased cardiovascular risk and CVDs incidence in PreHT individuals. Moreover, the prognostic significance of assessing endotehlial dysfunction in hypertension (as well as in PreHT) is yet to be established.
This study is a retrospective study trying to find the predictive factors for medullary thyroid aggressiveness in terms of tumor metastasis and patients' survival.
The aim of this study is to evaluate the effect of glucagon-like peptide-1 (GLP-1) receptor agonist semaglutide on disordered eating behaviour in patients with overweight and type 2 diabetes. The investigators will also evaluate serum concentrations of incretin hormones GLP-1 and glucose-dependent insulinotropic polypeptide (GIP), as well as glucose variability using continuous glucose monitoring (CGM) devices before and after semaglutide, and determine his influence on eating disorders. In this prospective study the investigators aim to recruit 60 patients with type 2 diabetes and randomize them based on the presence of a disordered eating behaviour diagnosed by a validated questionnaire (1:1). Patients with a disordered eating behaviour will further be randomized (1:1) to receive semaglutide. At baseline and after 12 weeks of semaglutide therapy, the investigators will reevaluate glucose variability over 14 days using a continuous glucose monitoring device (CGM). With this study the investigators will determine the impact of GLP-1 receptor agonist semaglutide on disordered eating behaviour in patients with overweight and type 2 diabetes. This study will contribute to the knowledge about the role of incretin hormones and glucose variability in eating disorders in this population of patients.
The study hypothesis is that the rate of inadequate surgical margins after conservative breast surgery for DICS and the rate of reoperation (re-excision or/and mastectomy) is lower in the group of patients who underwent standard preoperative mammography and CEM to assess the extent of DICS, compared to the group of patients for whom the preoperative assessment of the extent of in situ breast cancer was not performed using one of the imaging techniques with contrast medium such as contrast mammography or magnetic resonance imaging.
The goal of this clinical trial is to compare two different, market approved, cryoballoon devices for the treatment of paroxysmal atrial fibrillation (AF). The main aims of the study are: - to compare the efficacy of two ablation devices (acute and 1 year success rates) - to compare the procedural characteristics (procedure duration, fluoroscopy duration, ablation time - to compare the complication rates Participants who have indication for cryoballoon ablation of AF will be randomized in 1:1 fashion to older fixed size cryoballoon and newer expandable cryoballoon. Standard of care cryoballoon procedure will be performed alongside with standard postprocedural follow-up. • to compare the complication rates Participants who have indication for cryoballoon ablation of AF will be randomized in 1:1 fashion to older fixed size cryoballoon and newer expandable cryoballoon.
Myrkl is advertised as a dietary supplement for use before alcohol consumption that is effective in prevention of side effects during the next day. With this research, the investigators want to determine the impact of the mentioned dietary supplement on the intestinal microbiome. For this purpose, the research was designed in three phases before, during and after the research as a double blind trial. In doing so, the subjects take a stool sample before and after the intervention and during the intervention, fill out questionnaires and undergo cognitive tests. At the same time, they give a blood sample after the intervention. After the results of the analysis are due, the researchers enter the data into the for that the predicted Access table (rel. representation of genera/genera/species, average results by questionnaires). The entered data is processed as part of statistical analysis.
The improvement or preservation of quality of life (QoL) is one of the three pillars of the European Union (EU) Mission on Cancer, which underpins the needs of patients from cancer diagnosis throughout treatment, survivorship, and advanced terminal stages. Clinical studies and real-world data show that the use of Patient Reported Outcome Measures (PROMs) for QoL assessment in routine oncology practice has positive effects on patient wellbeing and healthcare resource utilization. However, full implementation of PROMs is not yet part of standard of care and is not adequately considered in cancer policies and programs. A comprehensive tool incorporating the perspective of patients at different stages of the disease trajectory and widely applicable across Europe is still lacking. The European Oncology Quality of Life Toolkit (EUonQoL-Kit) is a unified patient-centred tool for the assessment of QoL, developed from preferences and priorities of people with past or current cancer experience. The EUonQoL-Kit includes three electronic questionnaires, specifically designed for different disease phases (patients in active treatment, survivors, and patients in palliative care), available in both static and dynamic (Computer Adaptive Testing, CAT) versions and in several European languages. This is a multicentre observational study, with the following aims: - The primary aim is to perform the psychometric validation of the EUonQoL-Kit. - Secondary aims are to assess its acceptability, to validate the CAT version, and to provide estimates of QoL across different European countries. The EUonQoL-Kit will be administered to a sample of cancer patients and survivors from 46 European cancer centres. The sample will include patients in active treatment (group A), survivors (group B), and patients in Palliative Care (group C). Each centre will recruit 100 patients (40 from group A, 30 from group B, 30 from group C), for an overall sample size of 4,600 patients (at least 4,000 patients are assumed to be enrolled, due to an expected lower recruitment rate of 10-15%). Three sub-samples of patients (each corresponding to 10% of the total sample for each centre) will fill in an additional questionnaire: - EORTC QLQ-C30, to test concurrent validity. - Live-CAT version, to test the feasibility of such implementation. - EUonQoL-Kit, 2-7 days after the first completion, to assess test-retest reliability.
The aim of this study is to determine the effect of repetitive tactile stimulation compared to selective stimulation on oxygenation of the infant at 5 minutes after birth. Infants born before 32 weeks of gestation will be included in this trial. This is a stepped-wedge cluster randomised controlled trial. The participating centre, rather than the individual infant, will be the unit of randomisation. This design is appropriate to test the effect of an intervention that encompasses a behavioral aspect - in this case the performance of tactile stimulation.
